When on a dig along England’s eastern coastline (near Scarborough, North Yorkshire), a group of archaeologists came across a crayon that's been aged 10,000 years. This Stone Age "sharpened stick of red ochre" is likely to have been for making markings on various surfaces, though that's not the only possibility. Measuring less than an inch, the crayon could have also been used to paint the body in a kind of sunscreen, as a disinfectant or "used ritualistically, as a part of burial ceremonies."
